The United States recorded 2,419,921 deaths in 2003 in a population of 290,809,777. What is the crude mortality rate per 100,000?
A83.2 per 100,000
B8,321.0 per 100,000
C8.3 per 100,000
D832.1 per 100,000
Answer & Solution
Correct answer: D. 832.1 per 100,000
1. The crude mortality rate is all deaths over the size of the population they occurred in.
2. 2,419,921 divided by 290,809,777 equals 0.008321.
3. Multiplying by 100,000 gives 832.1 deaths per 100,000 population.
4. 83.2 uses a multiplier of 10,000 and 8.3 uses 1,000, so both understate the rate.
5. 8,321.0 uses a multiplier of 1,000,000, which overstates it by a factor of 10.
